This application is a division of my application filed October 26, 1925,Serial No. 64,735.

in object of this invention is to provide a device in which stacks 0rtiers of receptacles are lodged to be singly delivered from time to timeas required.

Another object is to provide an improved mechanism whereby a single cupwill be delivered to an operator who has set a cup vendmechanism inmotion.

A feature of the invention lies in the novel arrangement of gearoperated cams, so that a single cup will be separated from its stackedcompanions and delivered to the operator.

Another feature of my invention lies in the novel use of cams to supporta stack of nested cups in a magazine.

Still anoth'e feature of invention lies in the means used to act uponand enter between the rims of the stacked cups so that the lower cup ofthe series is wedged apart and separated from the remainder of the cups.

Advantages of my invention are, relative simplicity of construction,certainty of operation. undamaged merchandise and sanitation.

The accompanying drawings illustrate the invention in form at presentdeemed most desirable.

It will be obvious that the cup dispensing means is per se an inventionand maybe operated. if desired, separately from any drink dispensingmeans or coin controlled mechanism. For such latter operation it is onlynecessary to malre the shaft 15 continuous between the handle 7 and gear17, in other words, to eliminate the intended to be bridged by the coin.cup will then be dispensed at each turn of the handle and no coin needbe inserted, in fact no coin slot is then necessary. If the coincontrolled parts are eliminated the cup vending device may be operatedeither with or without the liquid dispensing device attached thereto.

Hence the cup vending mechanism which is ings of the present applicationa coin-controlled drlnk vending mechanism is illustrated designed tovend a drink consisting of two component parts; v1z., a syrup and acharge of carbonated water delivered under pressure and mixed with saidsyrup by the machine at the time of its delivery therefrom.

It is intended that in common use the machine'a will preferably behoused in a cabinet K, a fragment of which shown in Fig. 5, and thatonly part of thefront of the machine will be exposed to view, while theremainder of the machine is covered by the cabinet to prevent tamperingwith or injury to the machine proper. e

The cast metal frame of the machine is shown as comprising base and topmembers 1 and 2 connected by struts 3 at either side, spaced apart andsecured to said base and top by cap screws 3a and 3b.

The base casting 1 is provided with a recess 4, which is open at thefront side and has a horizontal U-shaped forwardly open lip 4a uponwhich the vended cup 5 is received from the nested cups in the magazine28 in which the receptacles to bevended are supported prior to deliveryof the cup and reception of a drink therein.

A spout 5 takes care of the drip, and a chute 5" to receive the usedcups leads from the frame 1 to a suitable receptacle not shown.

The casting 1 is also formed with a vertical passage 6 opening down tothe recess 4, and through which the cups are delivered one at a timefrom a magazine to the lip 4a, by cup dispensing means, when the machineis operated. 7

The manually operated actuating mechanism comprises a hand crank 7 fixedto a horizontal shaft 8 that is journalledin a rib 1a at one side ofthebase casting 1 and projects from the rear face thereof, and that isthere and provided with a coin carrier 9, rigidly fixed to the crankshaft 8 by a pin 8 and to a bearing 10 that extends to a rib 11 of theframe; (See Figs. 6 and 14.)

' i 12 is a coin slot open to the front of the frame and is ofsufiicient cross section to receive and conduct a coin of thedenomination "in the rib 11.

required to pay for one of the cups to be vended.

The coin carrier 9 is preferably U-shaped and the open space 9 betweenthe limbs of seat 9a to seat a coin 13 to bridge the open space betweenthelimbs of the U to bear against and operate a lug 14 and retract atappet 14 when the crank 7 is turned for the purpose of operating thevending mechan1sn1.

The lug 14 and tappet 14 are fixed to, and extend on opposite sidesof,'a transmitting shaft 15 that is journalled in both limbs of thecarrier 9, and also in the bearing 10 and A'coilspringS is coileduponthe bearing sleeve 10 and is arranged to yieldingly hold thecoincarrier against the outside of'the frame member 1 in position to receivefrom the coin slot- 12 a coin13 to bridge the space 5 9' and to key thecoin carrier 9 to the lug 14 to turn the shaft 15, to which the lug 14is fixed by pin 15. (See Fig. 15.) Q

Said slot 12 is formed in the frame member 1, and extends from the frontface of said member to deliver a coin 13 into the coin seat 9a (see Fig.14) in the coin carrier when said carrier and other parts of the machineare in coin receiving position.

When there is no. coin in the coin seat 9a the crank 7 maybe oscillatedalmost throughout one revolution and the carrier stops against the frameat each end of its arc of travel.

The spring returns the carrier with considerable force to its stop onthe outside of the frame, and there is likely to be more or lessbattering of the frame or the carrier, thus misalining the seat withreference to the slot, and to correct this difficulty, adjustable stoplugs 16 in the form of screws are thread- .ed through the carrier toengage the frame so that when the contactlng surfaces become batteredthe coin seat may be again alined with the slot by screwing the stopsfurther through the carrier, thus causing the carrier to stop inposition to receive the coin from the coin slot. (See Figs. 8 and 9.)

TVhen the coin slot 12 is unobstructed and a coin of required size isdropped thereinto such coin passes down into the coin seat 9a and thenupon oscillation of the crank, the coin engages and causes the lug 14 toswing around, thus transmitting motion to the shaft is fixed on theinner end of the shaft 15.

'15, thereby revolving a bevel gear 17 which The' bevel gear 17mesheswith a gear 18 fixed to a vertical shaft -19,'which is jour nalledat the rear of the base member 1 in ears 20, prO ect'mg from saidmember, anc

is connected to operate the cup delivering mechanism detailed in Figs.12, 13, 14, 15 and 16.

A gear 21, (see Figs. 5 and 6) meshes with the gear 18 and is fixed toone section 22 of a horizontal shaft which is formed of two torsionallyconnected sections 22 and 22. A revoluble member in the form of a camwheel 23 is fixed to the section 22' and is arranged and connected tocomplete the operation of the cup delivering mechanism.

The lug and tappet l4 and 14:, vertical shaft 19, the cup deliveringmeans, and the cam wheel 28 are thus connected for coordinate operation.

A master spring preferably formed of two coils 27, eccentricallyconnected by crank pin 27 to the revolvable cam wheel holds said camwheel normally in a predetermined position,

nd the operation of the lug 1% by the coin is against the resistance ofsaid master spring and such resistance affords a friction on the cointhat tends to hold the coin in the coin seat while operating the lug.The coin enters the coin seat from above, and when the coin carrier isrevolved sufficiently to invert the coin seat, the coin would drop outif it were not for the friction caused by the resistance of spring 27,which is given tension by the initial rotational movement of the cam 28;and when the cam crank pin 27, by which the master sprin 27 iseccentrically connected to the cam 23, comes to dead-center as thespring swings across the axis of the cam, the stance of the masterspring to the advance of the lug under the pressure of the coin carriedby the coin carrier is so reduced that the friction on the coin would beinsufficient to uphold the coin, and the coin would drop out of theinverted coin carrier, thus leaving no connection between the coincarrier and the cam 23, so that the operation of the machine would notbe carried on.

To overcome this difficulty, the cam operating shaft is made in the twoalined sections 22 ant 22 and these sections are connected to each otherby a torsion coupling comprising an intermediate spring 22a the ends ofwhich are fixed to the sections 22, 22, respectively, by means ofsleeves 22?) and 220.

Said intermediate spring 22a is of such strength that when it is putunder tension by the resistance of spring 27, as it approaches the deadcenter position, the reaction of said sprin 22a against the lug issufficient not only to frictionally hold the coin until the dead centerposition is reached, but also to suddenly thrust the cam wheel onwardafter spring 27 passes the dead center; and the moment this occursspring 27 operates to instantly turn the cam 23 to normal or initialposition where comes to res and is held in such initial position by thetension of the spring 27. V

The intermediate spring is so adjusted by means of screw (Z in thecollar 6 on the coupling sleeve 22?) which is fixed by pin f to theshaft member 22 that the tension of spring 22a will be sufficient toaccomplish the results above set forth. he cam 23 when returned tonormal position also returns the gears 21, 18 and 17 to a pre-determinednormal position and the lug 11, being fixed to shaft 15 which is fixedto gear 17, will bepositioned so that lug 14 will be just in front ofthe coin seat 9a in order that a coin may be easily received in saidseat.

When the spring 27 passes the dead center and spring 22a returns tonormal position, the lug 14 is withdrawn from the coin so that the coinis free to drop by gravity from the coin seat 9a. Further movement ofthe cam 23 by spring 27 revolves shaft 15 and moves the tappet llagainst the coin to positively 11' k the released coin out of the coinseat in the event the coin has not previously fallen therefrom bygravity.

The shaft member 22 is journalled at one end in a block 24;, and theother member 22 is journalled in a casting 25 depending from a casting26 secured to the bottom of the casting 2. (See Figs. 5 and 6).

The spring 27 secured to the eccentric cam pin 27 on the cam wheel 23and to the frame,

ieldingly holds the said wheel 23 and its connections at the restposition, and it not only operates the tappet to eject the coin, butalso operates means to dispense cups.

The crank is only oscillatable and stops short of a complete revolution,as indicated in Fig. 1, and the gears 17, 18, 21 are so arranged thatthe cam wheel 28 can be turned to a point somewhat more than 180 degreesfrom rest by operation of said cranlr and before the crank reaches thelimit of its movement the cam wheel and the tappet are automaticallycaused by reaction of spring 27 to complete a full revolution on and toreturn to rest to complete the cup vending cycle of operation.

Said. spring 27 is arranged in two upwardly diverging sections or limbs,one of said sections being secured at its upper end to the fasteningelement 27:0 and the other of said sections being secured at its upperend to the fastening element 27.2. The fastening element 2750 is on oneside of a perpendicular plane drawn along the axis of rotation of thecanr23,"and the fastening element 272 is located on the other side ofsaid plane, said fastening elements being enough apart to stabilize theaction of the spring sections 27 upon the pin 27 of the cam 23, thusyieldingly but positively normally maintaining said cam at rest in theposition sho'wnin 5, and automatically restoring such cam to saidposition of rest after the shaft upon which it is mounted has made acomplete'rotation and the cycle of operations which accompanies thevending of a 'cup has been completed.

The cup dispensing device comprises a magazine 28 mounted on andstationary to the casting 1 and has a circular cup-way 29 aboveandaxially aligned with the passage 6, and having a chamfered internalflange 30 below which thin mutilatedv worm-rimmed orperipherallythreaded revoluble cup feeding disks 31, are arrangedto'support a stack of nested cups Gin the magazine. Said disks aremounted on shaft-s 32 and 32 and are arranged to be revolved relative tothe magazine. They are arranged with their spiral peripheries projectinginto the cup-way 29 to unitedly support the rim flange of the lowermostcup at one part of the revolution and the spiral peripheral grooves insaid disks are adapted .to receive the rim flange of the lowermost cupand move such rim down and thus cause the cup to drop into the verticalpassage 6 when the disks are turned to the appropriate position for supporting the next cup Hm. I

Preferably there are three of such disks symmetrically disposed, asshown, and in fixed relation to respective operating gears.

A gear 33 and its disk 31 are in fixed relation to shaft 32, and thegear 33 mesl es with an annular gear 34, which is journalled on adepending collar 35 on the flange 30 and is initially revolved by powerapplied through the hand crank 7. Disk gears 36 and 37'are fixed to theother disks 31, and mesh with the ring or annular gear 34 to be revolvedthereby; so that all three disks revolve alike when the shaft 32 isrevolved.

As shown in Figs. 9 and 12, the cups C have flanged rims Z) and arenested one within another in the chamfered flange 30, with the flange bof the bottom cup resting on the disks 31. As these disks rotate, theirthread- ,ed peripheries receive and engage the flange Z) of the bottomcup and move it down until the cup drops through the passage and restson the lip 4a in the recess 4.

The rotation of the disks 31 is effected through train of gearscomprising gear 39 fixed to shaft 19, and meshed with gear 40 that isfixed to shaft 41,.to which is fixed gear 42 that is meshed with gear43, fixed to shaft 32 which turns gear33 that revolves annular .gear 34,by which the disk gears 36 and 37 are revolved. lVhen the crank istufrned, with coin in place, the shafts 19 and 41 will be turned, andalso the gear 43 and thus revolve the annular gear 34, and the disks 31will be simultaneously rotated to dispense a cup. The cam wheel 23 onshaft member 22 is turned through an arc tostretch the spring 27 whichinstantly completes the revolution passes dead of the shaft 22, when thespring center. Owing to the manner inwhich the springs 27 and 22acooperate to give a sudden for.-

ward impulse to the cycle of movements which accompany a completeoperation of the crank 7, the three threaded gears which propel the cupsC downwardly are simulta neously quickly rotated during the latter partof each cup-delivery movement, thus safeguarding the cups from stickingand causing them to be quickly and positively thrown down upon the lip4a in the recess 4.

A counter 44 (see Fig. 1) is operatively connected to one of the shafts32 and records the number of cups-dispensed by the machine, andtherefore the number of times it is operated. 7

Means are provided to prevent the insertion of a coin when the supply ofcups is exhausted, and such means comprise a spring actuated coin stopoperating arm 45 (see Fig. 8) that is pivoted intermediate its ends at45 and is provided at one end with finger 46 constructed and arranged tobe pressed into the slot to be withdrawn by the operator.

In this way when the last cup is dispensed from the stock so that it isremoved from the part 46 0f the device, the spring 47 acts to move arm45 to insert the stop 48 and prevent loss of a coin by an intendingcustomer. 1

The friction of the finger 46 on the rims of the cups wouldv prevent thecups from moving down, and it is necessary to withdraw the finger fromthe cups duringthe o eration of dis ensin a cu and this is efi. .e'

fectedby a pin 49 normally retracted by a spring 50 and adapted to beinserted into slot 12 through a hole, and into engagement with the stop48 to push said stop back to oscillate arm 45 and retract the finger 46from the cup; a lever 51 (see Fig. 15) fulcrumed to frame at 52 has afinger 53 operableby a cam 54 fixed to thecrank-shaft 8, to push the pin49 into the positionfor retracting said finger 46 after a coin has beendroppedinto the coin carrier, and directly after-the crank 7 has. beenmoved to turn the coin carrier and the cup dispensing device. When thepin 49 has been moved into engagement with the stop 48 it has passedtransversely through the coin slot 12 so that another coin cannot beinserted in said'slot and also provides a means for requiring the handle7 to be in initial position when a coin isinserted and thereby assurescorrect positioning of the 1.1:?

coin carrier relative to the slot 12 when the coin is inserted. I I

The cam 54 extends around the axis of the shaft 8 suflieiently to holdthe, lever 51 and pin 49 in finger retracting position throughout allexcept a limited initial arc of the crank oscillation, so that while thecup feeding disks 31 are lowering the cup, the finger 46 is heldretracted from the path of the projecting cup rim, but when the crank isreturned to its initial position shown in solid lines in Figs. 1 and 1%,the spring 47 again presses the finger 46 against a cup, and the stop 18is withdrawn from the coin slot so long as cups are in the cupreceptacle, and when the cam 54 is withdrawn from the lever 51, thespring withdraws the pin 4&9 from the coin slot 12 leaving said slotfree for the insertion of another coin.

The drink dispensing mechanism is contained and supported i a hollowcasting 55 having a cover plate 56.

A fountain tray 57 is provided and a fountain or jar 58 is invertedthereon. A tube leads from the tray 57, being secured to the casting byscrews threaded into flanges 66. Said tube opens into an inta re chamber61. which in turn, opens into a measuring or pump cylinder chamber 62.Said chamber 62 communicates with outlet chamber 64-.

through a duct 65. Said chamber 64 h an outlet 66 that alines with atube 67. A vent 68 at the top of chamber 61- admits air to preventsiphoning of liquid from the jar 58.

A rod 69 having a valve 7 O thereon extends through the castings 26 and2, and has at its lower end an anti-friction roller 69 that rests on thecam wheel 28 to ride the cam and be raised thereby. Said cam causes thevalve 70 to temporarily close the passage 71, which leads from thebottom of a pressure and float chamber 7 2 into the expansion chamber 71in the casting 26. Near the top of its upward stroke and after the valve7 O is seated, and the cam 23 is moving during the spring retractingportion of its revolution, the valve stem 69 lifts a valve stem 7 3,having a spring 77 therearound. and unseats a pressure liquid inletvalve 74, thus permitting the pressure fluid to flow from the fitting 75, through the cage 76 and thence into the chamber 72, while the outlet71 is closed by valve 70.

The pressure tank 78 is connected to the fitting by a suitable pipe 79.During the time that the inlet valve 7 4 is open and the outlet valve 70is closed, the stem 81 is lifted by means of its float 80 until saidfloat by means of a valve 83 closes a vent 81 in the cover 56. A spider82 aids in guiding said float stem 81. Said vent 81 communicates withdiverging vent holes 84 to allow free escape of gas until the float 80and the vent valve 83 are lifted.

Jam-nuts 85 screwed onto the float stem 81 are adapted to normally reston cover 56 and to support the float close to the top of the chamber 72.

lVithin casting 55 is a threaded bore which receives a nipple 86 andwhich is also adapted to receive the valve seat bushing 87 having at itsupper end the cage 76 and provided with outlets 87. The valve stem 7 3extends down through the cage 76 and bushing 87, which is provided witha gland 87 which is shouldered to receive the thrust of the spring 77,which operates between the shoulder of the gland 87 and the collar 7 3fixed to the valve stem 73. Pressure chamber 72 communicates through aport 88, (Figs. 5 and 7), with a cylinder bore 89, that is axiallyaligned with and is of less diameter than the syrup pump cylinder.

A cylinder head 90 at the lower end of the bore 89 prevents the pressurein here 89 from flowing into the syrup chamber 62 and a piston rod 91extending through such cylinder head is provided below such head in thesyrup chamber 62- with a syrup lifting head 92.

The mixing tube or outlet 9% extends from the expansion chamber 71through a hole 95 in the rear of the casting, and delivers the fluidsthrough the outlet spout 38 into the cup C previously delivered to andresting on the lip 4a.

The tube 9% is so steeply aslant that the liquids discharged thereintowill flow out of the spout 38 with suflicient velocity to shoot overinto the cup C, but the spout terminates su'lf ciently behin d the frontrim of the drip cup to allow any drops which may drip from the end ofthe spout to drain out through the drain pipe 5 without smearing the lip4a or the rim Z) of the cup.

The pressure liquid outlet valve-lock releasing arm 96., fixed by a pinto the rod 91, is movable up and down by said rod 91 and is adapted tolift the outlet valve releasing rod 97, which is provided with anadjustable stop formed by nuts 97 on said rod 97.

Said stop isnormally spaced from the arm 96 as indicated in Fig. 5 sothat when the power piston 93 is operated by pressure from the chamber72, the arm 96 will operate with lost motion to lift the rod 97 at theend of a measuring stroke of the syrup pump piston 92.

The rod 97 has a collar or tappet 97 a which is adapted and arranged tolift the operating arm 98of the rocking valve lock which is pivoted tothe casting 2 by the pin 99 ad acent the valve rod 69. Said rod 69 isprovided with a shoulder 100 under which a lock limb 98 of the valvelock may be moved by the spring 101 when the valve rod 69 is elevated bycam 23 to cause the valve 70 to close the outlet 71.

When the arm 98 and its lock limb 98' are in looking position,.the valverod 69 and valve 70are held to positively close the outlet 71; and whenthe arm 96 lifts the rod 97 and its tappet 97a to the position indicatedin Fig. 6a the valve rod 69 is free to be loweredandis so shown in Fig.5a.

The unlocking rod 97 is guided in the cover 56 and the guide 102 whichis stationary to-the casting 55, and the spring 101 operates be tweenthe guide102 and a washer 102 resting against the arm 98 and under thespring 101 to normally force the look into locking position. 103 is anut on the rod 69 to clamp a bracket 104 onto the set nut 104 on saidrod 69. .Said bracket is slidable up and down on the rod 97 so that whenrod 97 is forced up by pressure on the piston 93 from the chamber 72 thespring 105 on the unlocking rod, 97 acts through the bracket 10a afterlock 98 is released to force down the valve rod 69, thus to open outlet71 from the pressure chamber and permit the liquid therein to flow bygravity into theexpansion chamber 71. The roller 69 is thus brought torest on the cam wheel 23 and the parts remain in the position shown inFig. 7 until another operation of the crank serves to turn the cam 23and again lift the roller 69, the valve 7 0 and valve 74. The operationof the invention is as follows: v

A coin of the required denomination is placed in the slot 12 and runsdown into the grooves 12 and seats in the seat 9a of the coin carrier,providing means for connect in" the shafts '8 and 15, thus bridging theopening between the limbsof the coin carrier.

The crank 7 is then turned to the right in Fig. 14 and the coin engagesthe lug 14, (see Figs. 13, 14 and 15), and turns the shaft15 and gear17, thereby turning thegear 18, its shaft 19, the gear 21 and its shaft22, and, acting through the spring'22a (see Figs. 5, 6, and 15), turnsthe shaft 22 and the cam sheet 23. The oscillation of the crank 7issufficiently ample to turn the-crank pin 27 in the di rection of thearrows on and adjacent the cam wheel in Figs. 5 and 6, until the crankpin has swung down and passed a vertical, not shown, drawn from thehorizontal axis of the cam wheel 23, when the manually tensioned spring27 operates with a snap action to suddenly complete the revolution ofthe cam wheel to drive the gear 21 in the direction inwhich it wasturned by the crank, thus completing the revolution of said gear 21 andthe train of gears and shafts connected therewith.

'The snap action revolution of the gear 21 operates the gear 17, shaft19, gears 39 and 4:0, shaft 11, gears 42 and 43 and completes therevolution of the cup delivering wheels 31, sothat when the cam 28 comesto rest a cup 0 has been delivered and hangs suspended by its rim 1) onthe lip 1a.

The beverage delivery mechanism is timed to operate during the portionof the movement of crank 7 which follows the delivery of a cup to theposition for being filled. As this mechanism, separately considered isdescribed and claimed in my original application and forms no part ofthe present application a' more detailed description of its action isnothere required.
